I applaud the spirit of your endeavour. I like the style in which you write.

It is a very clear example-driven practical approach to understanding Python, one of the most powerful programming languages from the open source community.

- John Popplewell (john-at-johnnypops-dot-demon-dot-co-dot-uk)

Thank you for amazing work 'A Byte of Python' !

- Zhou Xiaohu (zhouxiaohu-at-263-dot-net-dot-cn)

Excellent work!

- Jaroslaw Zgoda (jaroslaw-dot-zgoda-at-generali-dot-pl)

(The following quote was automatically translated from French to English using Google!)

"Having bought various works treating of initiation with Python, I found insipid and rather intended them for developers confirmed in other languages which would wish to approach Python.

Today I finally found the book that I need, simple and didactic, really intended for nonprogrammers and approaching most of the characteristics of this language, while making comparisons with other languages of less high level, such as C, C++, C #, Java.

The most pleasant surprise is that this book, 'A Byte of Python' is free, consultable on line or to download. To even judge by you..."

I have also received very good feedback about 'A Byte of Python' from Eric S. Raymond (who coined the term 'Open Source' and whose article inspired me to learn Python in the first place), David Mertz (author of 'Charming Python' column) and Bruce Eckel (author of 'Thinking in C++' and 'Thinking in Java').

Official Recommendation

"A Byte of Python" has been listed on the Official Python website under the 'Full Tutorials' section, second only to the official documentation written by Guido van Rossum (the creator of Python) himself!

Icelandic

Dagur Pall Ammendrup (dagurp-at-heimsnet-dot-is) is in the process of translating the book to Icelandic language! Here's a little background information on Dagur and why he wants to translate "A Byte of Python" to Icelandic:

"My background... Well I'm a computer science student at the University of Iceland. I want to translate the book into Icelandic because I think that Python is the perfect language for beginners and there's almost no documentation in Icelandic for any programming language available on the web. I have an 11 year old sister who is interested in programming and I think this tutorial will be perfect for her once I've finished translating it."

Spanish

Cristian F. Prieto (cprieto-at-info-servicios-dot-net) is translating the book to Spanish.

One of my readers is translating the book to Danish. (He wishes to remain anonymous for the moment)
